CVE-2026-31739

High
Published: Translated: NVD NIST

Summary

A vulnerability has been identified in the tegra crypto driver in the Linux kernel, which involved the failure to set the CRYPTO_ALG_ASYNC flag for asynchronous algorithms. This led to the crypto API selecting these algorithms for users requesting only synchronous algorithms, potentially causing crashes.

Risk Assessment

This vulnerability may lead to system crashes, affecting the stability and availability of services within the organization. Users may experience unexpected interruptions in applications relying on these algorithms.

Recommendation

It is recommended to update the Linux kernel to the latest version to mitigate this vulnerability. Additionally, monitoring systems for potential crashes related to this issue is advised.

Original NVD description (English source)

In the Linux kernel, the following vulnerability has been resolved: crypto: tegra - Add missing CRYPTO_ALG_ASYNC The tegra crypto driver failed to set the CRYPTO_ALG_ASYNC on its asynchronous algorithms, causing the crypto API to select them for users that request only synchronous algorithms. This causes crashes (at least). Fix this by adding the flag like what the other drivers do. Also remove the unnecessary CRYPTO_ALG_TYPE_* flags, since those just get ignored and overridden by the registration function anyway.
